GEARING.

Application filed April 19, 1919. Serial No. 291,182.

To all whomit may concern.

Be it known that I, JAMES V. E. ERICK- soN, a citizen of the UnitedStates, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certam new and useful Improvements in Gearing;and I do hereby declare that the following is a full, clearpand exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification. I

This invention relates to improvements in gearing and" consists of thematters hereinafter described and more particularly pointed out in-theappended claims.

The improved gearing is of especial advantage for use in connection withwashing ,machines of the oscillating cylinder type,

such as is shown in the patent to Gustav B. Keil, No. 1,245,109, ofOctober 30, 1917, and it is herein illustrated and described as appliedto such a machine, but as is apparent,

the improved gearing may be used in other types of washing machineswhere its peculiar characteristics make it advantageous to do so.

The advantages of the improved gearing will be more apparent as Iproceed with my specification. I

In the drawings:

Fig. 1 is a view representing a front end elevation of an oscillatingcylinder washing machine to which the improved gearing has been applied.

Fig. 2 is a view representing a longitudinal, vertical section throughthe same, the

plane of the section being indicated by the line 22 of Figure 1. Fig. 3is a new representing a transverse, horizontal section through one endof.

the washing machine, the plane of the sec tion being indicated by theline 33 of fi ig. 4 is a view in elevation andon' an enlarged scale, ofthe improved gearing, shown as removed from the rest of' the mechanismof the washing machine.

Fig. 5 is a detail sectional view on an enlarged scale, through a partof the gearing shown in the right hand end of Figure 2.

Fig. 6 is a detail, horizontal, sectional view on an enlarged. scale,through another part of the gearing, the plane of the sec- ;ion .loeingindicated by the line 66 of 1 fi-eferring now in detail to that embodi-Speciflcation of Letters Patent. Patented F b. 1, 1922 i ment of theinvention illustrated in the accompanying drawings :10 indicates a mainsupport for the gearing which, as illustrated, 1s the tub of a washingmachine of the oscillating cylinder type. Said .tub is mounted at itscorners upon front and rear pairs of uprightlegs 11' and 12respectively. Said legs are made of angle bars, so arranged that theangles thereof define the corners of the support. The front pair of legs11 are connected together at their top ends by an angle bar 13 and allthe legs 11 and. 12 are connected together near their bottom ends by thechannel irons-14, which act to rigidly brace the legs.

, The tub10 is inade of sheet metal and includes a transversely roundedbottom wall 10 which blends into upright side walls,

and upright front and rear end walls 10,

10, respectively, said front wall being spaced 'rea-rwardly from thefront legs 11.

v A cover'15 is hinged to the topedge of said rear wall. A horizontalplate 16 which is interposed between the angle bar 13 and the.

front wall 10", forms a top closure for the space between said frontlegs and front wall. A second ilate 17 is-fixed to the front face of theang e bar 13 and to the bottom edge of saidplate is hinged an apron 18which has a spring catch at its bottomedge, to engage and lock with thechannel iron 14 that connects the front legs 11 together.

Within the tub 10 is mounted a cylinder 19 which is adapted for anoscillating movement in said tub. Said cylinder is of the usualstructure for. washing machines and includes a lid 20 which may beremoved for the purpose of placing. the clothin to be washed in thecylinder. Fixedto t e rear upright wall of said cylinder in a planeabove its center of gravity, is a. trunnion 21 which is removablyjournaled in an upwardly opening groove of a yoke 22 fixed to therearwall 10 of the tub 10. To the front wall of the cylinder is fixed abearing plate 23 which is capable of a detachable operative engagementwith theinner end of a horizontal, power-driven, rotary, oscillatingstub shaft. 24, which projects through the front wall 10 of the tub, inaxial'alignment with the trunnion 21. When the shaft 24 is at rest, thecylinder 19 may be removed from the tab 10, by lifting it fromengagement with the shaft 24 and bracket 22, the lid of the tub, ofcourse, being first opened to persuch removal.

The front wall 10 of the tub, together with the plate 16, and apron 18,defines a compartment 25 locatedlwi'thin the plane of the front legs 11.in said compartment is located the power driven gearing which impartsthe oscillating movement to the cylinat the left hand end of the body,are fixed to the other oi said front legs. Between its ends, and at thetop of the bracket 26, is prov ded an over-hanging, forwardly exam a 31,which terminates in a dcpending flange 32, so arranged as to receive andprovide bearing for the outer end of the stub shalt 2d, the inner end ofwhich extends through and has bearing in a boss 33 termed on the body ofsaid bracket.

34 indicates a forwardly extending, horirental stub shaft fined in thebody 27 of the bracket 28 in a plane parallel with the opera shaft 24;,and on this shaft is ro- ,tatively mounted a spur gear 35. The teeth oilsaid gear mesh with the teeth of aworm gwr 3d fixedto a; horizontallydisposed shaft 37 ed at an angle to the plane of nr gear. Said shalt hasbearing near its ends insleeves 38, 39, made integral witha r 'w platevd0 bolted to the bracket body 2'2,

lw the gear 34. This shaft 37 is connected by'a coup w 1' 41 to thearmaand, wanna with the eat of the shaft 42 of an electric motor 43which is r a ded in an inverted position from a plate or d lhthatextends torwardl from the, body 2? of the bracket 26, in a insubstantially, vertically below the overeion" 31 before referred to.

Thmtor 3 is adjustable with reference to the flange 44 so that itsarmature'shait may. be m with reference to the worm shalt 3'8. In theboa sleeve38is nnnntifriction bea 38 to take up the end of said-shaft37. (See ]Fig. 6.) e -l g plate includes an oil cup 45 in whichislocatedfa spur gear 46, loosely mounted on a stud 4L7. This rpreternlily is inarle with teeth of felt or e niaworin 3d and-act as awiper on said worm to hrorfdhtthe throwing or lg of 6 lubricating oilmaintained in said cup for the purpose of lubricating the worm gear.

'AS the worm gear is driven at a one to one meshes with and actuates asegmental gear 49 fixed to a clutch sleeve 50 loosely mounted on thereduced outer end part 24? of the shaft 24. This clutch, sleeve (seeFig. 5) is held against .endwise movement on said shaft, by reason ofits engagement between the bearing flange 32 and a shoulder 24 formed atthe junction between said reduced outer part 24 and the inner end part24: of greater diameter, of said shaft. Between its ends, one side ofthe clutch sleeve 50 is flattened or broached to fit ina similarlyshaped hole in the segmental gear 49, and a set screw 49 rigidly securessaid gear on said sleeve.

The rack bar 48 is held in engagement with the segmental gear 49 by a.swinging basket 53 which has a bearingsleevc 54: in

vwhich the rack has sliding bearing, and by spaced front andrear'apertured arms 55 that embrace and have pivotal bearing on the endsof the clutch sleeve 50, on either side of the hub of the gear 49. Theinner end part 24 of the shaft 24:, is broached on one side as at 24,and on said inner end part is slidabl and non-rotatively mounted aclutch co ar 56 which may be shifted endwise on said shaft, into and outof engagement with the adjacent end of the associated clutch sleeve 50.In said clutch collar is an annular groove 57 adapted to receive the endof a clutch shifting lever 58 (see. Fig. 1) mounted on the inner end ofa rock shaft 59. This rock shaft is iournaled in suitable bearing lugson the bracket 26 and has its outer end extended beyond the left handside wall of the machine, where it isprovided with an operating lever60. v

The operation of the parts thus far described, 18 as follows:

When the motor is rug, it will drive the rack bar 48 which willoscillate the segmental gear 49 and clutch sleeve 50- to 80 will producean :i lement or disengaent between the clutch collar- '56 and the clutchsleeve 50, so that when said which it is attached. Actuation of thelever collar and sleeve are enged, an oscillat ing movement is impartedto the shaft 24% which in turn will impart a like movement to thecylinder 19. \Vhen the clutch collar and sleeve are disengaged, and themotor is running, the segmental gear and clutch sleeve will oscillate onthe shaft 24 withoutimparting any movement to it.

The gearing for driving the wringer mechanism is as follows:

:Rotatively mounted on a stud on the bracket 26, in a plane above thegear 35, is a combined spur and bevel gear 61, the spur gear part ofwhich meshes with the gear.

35. The bevel gear part of said combined gear meshes with oppositelyfacing.

gears 62, 62, loosely mounted on a horizontal shaft 63 journaled in thebracket 26.

The opposed faces of said bevel gears have clutch members which areadapted to be engaged by a clutch collar 64, keyed to slide on saidshaft between said gears. Said collar 64 is actuated by a bell cranklever 65 pivoted on a stud 66 on the bracket 26, above the combined gear61. The horizontal arm of said lever 65 projects beyond the adjacentside of the machine where it is connected by a link to a shifting lever67 pivoted on a stud carried by abracket 68, rigidly secured to i themachine above the adjacent front leg 11.

To the outer end of the shaft 63 is fixed a sprocket 70 which, through achain 71, drives the shaft 72 of a clothes wringer 73, rigidly securedto the angle bar 13. It is apparent thatby shifting the lever 67, thewringer may be driven in either direction or may be stopped, even thoughthe gear 35 is being driven to oscillate the segmental gear 49.

. The improved gearing has many advantages. By setting the shaft 37 atan angle, a worm geardrive to the spur gear 35 may be provided, andplenty of room may be had in the compartment 25 for the driving motectedagainst breakage, or damage from such wash Water as may be spilled,during the washing operation. All of'the gearing may be assembled on thebracket 26 beforesaid bracket is secured in place Within saidcompartment. By the reduction of the number of parts used, frictlon andnoise are re duced to a minimum. The use of the Wiper gear 47 preventsthe splashing and throwing of oil, due to the high speed at which themechanism is driven.

I claim as my invention:

A gearing device of the kind described comprising, a support including abracket plate, a horizontal operating shaft journalled in the bracketplate, there being a horizontal outstanding flange on the bracket platebelow the operating shaft and afsecond shaft below and to one side ofsaid operating shaft, a-spur gear on said second shaft, meansoperatively connecting the spur gear'with the operating shaft forimparting an oscillatory movement'thereto, a

horizontally disposed worm journalled insaid worm extending in a planeat an acute angle to that of said spur gear, and a motor depending fromsaid bracket flange and directly connected to said Worm.

In testimony, that I claim the foregoing as my invention, I aiiix mysignature in the presence of two witnesses, this 15th day of April, A.D., 1919.
